Several types of foundation
in tension for structural membranes with different
materials, geometries, manufactures, installation
s, efficiencies and depths were studied. As a
result, a better understanding of the uplift behavi
our and mode of failure have been acquired.
Therefore, the pull-out capacity of anchors ca
n be estimated confidently encompassing the
complex relationship between various modes of failure, anchor geometry and soil properties.
Tridimensional prefabrication of housing has been the object of much literature and few realizations. Finally, enough buildings have been constructed that they can be analysed on site in order to confirm or deny the expectations drawn from integral or nearly integral prefabrication. As we have observed their foundations, it was surprising to find that many or most of their foundations were constructed in si tu, even though prefabricated solutions exist in the industry. This article presents available solutions for prefabricated foundations, it critically describes the foundations of 30 modular housing recently constructed in Catalonia, and it analyses the advisability (or non-advisability) of industrializing the foundations of this type of building.

The ‘wine cathedrals’ were wine cellars built for agricultural cooperatives in southern Catalonia in the early twentieth century. They were developed by Cesar Martinell (1888–1973). As the cooperatives could not afford to build with steel or concrete, he used traditional masonry and drew on the achievements of contemporary modern architects such as Antoni Gaudi´, Lluis Dome` nech and Josep Puig. Martinell took advantage of the constructive and architectural possibilities of brick by using it not only for walls and pillars but also to replace main beams, joist beams, floor slabs and roofs. This gave rise to a type of building in which the constructive system becomes the architectural form and satisfies the technical and functional requirements. Some of the resources used by Martinell are still valid in low-cost and sustainable construction today when labour and local resources are more readily available than energy and imported products.

The Fifth Latin American Symposium of Tensile Structures was held in Santiago de Chile in September 2012. It was organized by the School of Architecture of the Pontifical Catholic University of Chile and chaired by the architect Juan I. Baixas. It was the fifth in a series of symposia that began in São Paulo in 2002, followed by Caracas in 2005, Mexico City in 2008 and Montevideo in 2011. Over three days, 6 lectures and 24 presentations were given to 161 participants from 18 countries and 4 continents. The main topics focused on recent projects, as well as new applications, basic concepts, features, materials, design, software, testing, installation and education.
